:The primary object oi' the invention is the;v provision'ot aV rim tool including .a pair oi grippinginenibers; Vadapted to engage the i j sidesct the deinciintable rim of an xion-riobile tire/or the like for theY purpose A further object of the invfntion vis the prov ion of a rim tool such Aas abovevreieired toivhich will be comparatively simple and inexpensive toiinanufacture, reliable and etlicient in use and readily operated. g.
